Abstract :
Orthogonal frequency division multiplexing (OFDM) is a well-liked technique for high data rate as well as high spectral efficiency. As a promising technology for next generation wireless communication, MIMO-OFDM has gained more wellbeing. In this paper, we have derived an analytical expression of signal to noise plus interference ratio (SNIR) and average probability of error in MIMO-OFDM system over Nakagami-m fading channel. It is found that the SNIR of MIMO-OFDM system decreases while increases normalized frequency offset. To increase the fading parameter m, the bit error rate (BER) performance for Nakagami-m fading channel has been reduced.
